Wikis provide users a shared workspace for creating and collaborating online. Wikis are typically used to collaboratively create resource material that can be easily edited, added to, and accessed via the Internet.  Wikipedia is one of the most famous wikis on the Internet, but wikis are also being used to create digital textbooks that are customized to the needs of the class. Wikis are great tools that make it easy for students to create individual and group projects that provide information that not only demonstrate learning, but also can be accessed and used by all class members and people around the world.
